SEAIVI FOR RAIN-COATS.

Specification of Letters Patent.

Patented May 2b, 11915.

Application led October 31, 1917. l Serial No. 199,459.

To all whom it may concern:

Be 1t known that I, RALPH R. SANDFORD,

' a citizen of the United States, and a resident of New London, in the county of Huron and Statel of Chio, have invented a new'and improved Seam for Rain-Coats, of which the following is a full, clear, and exact description.

The object of the invention is to provide-a new and improved seam for rain coats and other similar waterproof garmentsl and arranged to prevent the seam from accidentally opening and to render the seam watertight. A

ln order to accomplish the desired result, use is madeof a strip of fabric material overlying the overlapping seam sides of the garment, an adhesive substance between the contacting surfaces'of the saidhseain sides and the said strip, and stitches connecting the sides of the'said strip with the seam sides, the said vadhesive substance tilling the stitch holes.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification,

in which similar characters of reference indicate corresponding parts in both views. Figure 1 is a rear elevation of a rain coat providedv with the improved seams; and

Fig. 2 is an enlarged cross section of the y same on the line 2 2 of Fig. 1.

The material of which the body of the rain coat is made is preferably of two waterproof fabrics fastened together in the usual manner by an adhesive substance, and the coat is made in the usual parts connected with each other by seams 10, each of which has overlapping seam sides 11 and 12. of .Which the outermost seam side 12 is doubled up, as plainly shown in Fig. 2', and is conneCted with the other seam side 11 by stitches 13u Each seam 10 is overlaid at the inner face of the garment body by a strip 15 of fabric material and preferably. made double, that is,'of the same two fabric materials of which the body of the garment isv Une side edge 16 of the strip 15 is doubled under and the other side edge 17 is I made.

provided with a binding 18, and the contacting faces of the strip 15 and the corresponding seam sides 11 and 12 are connected with each other by an adhesive substance 20, such as cement. After the strip 15 is fastened in place by the adhesive substance 20 and While the latter is still in plastic condition the side edges of the strip 15 are fastened to the seam sides by stitches 25, 26, of which the stitches 25 pass through the doubled-up edge A16, and the stitches 26 nass through the edge 17 and its binding 18, as plainly indicated in Fig. 2L Now owing to the fact that the adhesive substance 2O is stillin plastic condition it is evident that the stitch holes formed by the needle are filled with some of the adhesive substance 2O thus rendering the stitch holes waterproof.

ln rain coats as heretofore made theseam strips were simply fastened to the seam sides by' an adhesive substanceI but such strips were liable to become loose with the wear and tear of the garment and the seams become correspondingly open. `With the improvement above described lthe seam strip the adhesive substance but also by the rows yof stitches 25 and 26, and in addition the stitch holes formed during the sewingoperation are illed with the adhesive substance, thus rendering the stitch holes as well as the seam completely waterproof. A seam made in the manner described. is exceedingly strong and durable and is not liable to open up even if the garment is subjected to considerable strain.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent "j 1. A waterproof garment having its body provided with overlapping seam sides, the outer seam side being doubled up and the doubled up portion stitched tothe inner seam side at a distance from its edge, a stripl formed of two fabrics fastened'together and of the same materialias the said body fabric, the strip overlying the said overlapping seam sides on the inner face of the garment, an adhsive vsubstance fastening the said seam strip to the said seam sides, and

4'stitches fastening the'margins of .the strip the sides of the said strip with the seam edge provided with a binding, an adhesive sides, the said adhesive substance filling the substance between the contacting surfaces 10 Astitch holes. of the said seam sides and the said strip, 3. In a Waterproof garment, a seam comand stitches connecting the said seam sides 5 prising overlapping seam sides, a seam strip With\ the tucked under edge and the said of fabric material overlying the said overbinding edge, the said cement filling the lapping seam sides, the said'seam strip havstitch holes. ing one edge tucked under and the other lRALPH ROSE SANDFORD.
